I'd suggest that your strongest points are:
1. "Traction trumps all." Demonstrable opportunity is the primary currency.
2. "Be a nice person." Successful people don't like to work with assholes.
3. "Prepare, and be brief." Anything that doesn't add significant value needs to come out of your pitch.
4. "Don’t be deterred by interruptions." These are opportunities. Think of these as buying questions. If they're asking you questions, they're telling you what you need to do to convince them to believe in you.
Good luck all in the next round or other endeavors!
From the written application that's supposed to be as terse as possible? I think I could get a feel for someone in person since I could dig into particular questions on the spot, but seems I'd have a real hard time judging meanness if I could only see the 1-way communication of the written YC application.
In general, the point was that humans usually make subconscious judgments before they even start talking to you; at the least, you should be aware of this.

However, people should at least be aware that humans rely on heuristics [1] to make sense of the world. In a positive sense, this means we don't have to stop and determine what a door handle is and what it will do every time we see one. In a negative sense, it leads to stereotypes that are usually incorrect.
Being aware of these will at least bring your attention to things you otherwise might have overlooked, such as having clean writing/grammar (conveys a sense of professionalism) or modifying your body language.
Would it be a combination of 1) demonstrating past successes gaining traction and 2) having a catchy prototype? Or are there other things?
Keep in mind that if the idea is novel and something people want, you'll get most of them converted no matter what if you initially promised that novel thing during the signup.
As somebody pointed out above, a "soon to launch" Web site, a large-scale survey with potential customers, a successful Kickstarter campaign, etc. provide some validation before traction.
If you have a track record of building products with traction, definitely discuss that as well (falls into the 'why you're the right team to execute').
